Kungani ibhuloho i-CMM ikhethe i-granite njengento yombhede?

I-CMM yebhuloho, eyaziwa nangokuthi umshini wokulinganisa wokuhlanganisa wohlobo lwebhuloho, iyithuluzi elibalulekile elisetshenziselwa ukukala izici ezibonakalayo zento. Enye yezingxenye ezibaluleke kakhulu ze-CMM yebhuloho impahla yombhede lapho into ezokalwa khona. I-Granite isetshenziswe njengempahla yokulala ye-CMM yebhuloho ngezizathu ezihlukahlukene.

I-Granite uhlobo lwetshe elivuthayo elakhiwa ngokupholisa nokuqiniswa kwe-magma noma i-lava. Inokumelana okuphezulu nokuguga, ukugqwala, nokuguquguquka kwezinga lokushisa. Lezi zakhiwo ziyenza ibe yinto enhle kakhulu yokusebenzisa njengombhede webhuloho le-CMM. Ukusetshenziswa kwe-granite njengento yombhede kuqinisekisa ukuthi izilinganiso ezithathiwe zihlala zinembile futhi zinembile, njengoba umbhede ungagqoki noma uguge ngokuhamba kwesikhathi.

Ukwengeza, i-granite yaziwa nge-coefficient yayo yokwandisa ukushisa okuphansi, okusho ukuthi ayinwebeki noma ifinyezeke kakhulu ngenxa yokushintsha kwezinga lokushisa. Lokhu kubalulekile ngoba ukushintshashintsha kwezinga lokushisa kungabangela izilinganiso ezithathwe yi-CMM ukuthi zinganembile. Ngokusebenzisa i-granite njengento yombhede, i-CMM inganxephezela noma yiziphi izinguquko zezinga lokushisa, iqinisekise izilinganiso ezinembile.

I-Granite nayo iyimpahla ezinzile kakhulu. Ayiwohloki ngaphansi kwengcindezi, iyenze ibe yinto ekahle yokusebenzisa i-CMM yebhuloho. Lokhu kuzinza kuqinisekisa ukuthi into elinganiswayo ihlala imile phakathi nenqubo yokulinganisa, kuqinisekisa ukuthi izilinganiso ezinembile ziyathathwa.

Enye inzuzo ye-granite ikhono layo lokudambisa ukudlidliza. Noma yikuphi ukudlidliza okwenzeka phakathi nenqubo yokulinganisa kungabangela ukungalungi ezilinganisweni ezithathiwe. I-Granite inamandla okumunca lokhu kudlidliza, iqinisekisa ukuthi izilinganiso ezithathiwe zihlala zinembe.

Sengiphetha, ukusetshenziswa kwe-granite njengento yombhede ye-CMM yebhuloho kunezinzuzo eziningi. Kuyinto ezinzile, enembile, futhi enokwethenjelwa eqinisekisa ukuthi izilinganiso zithathwa ngaso sonke isikhathi. Impahla imelana nokuguga, ukugqwala, kanye nokuguquguquka kwezinga lokushisa, okuyenza ibe inketho efanelekile yendawo enzima yelebhu ye-metrology. Sekukonke, ukusetshenziswa kwegwadle njengempahla yombhede kuwukukhetha okuhlakaniphile kwanoma iyiphi inhlangano edinga ukukala okunembile nokunembile kwezinto ezibonakalayo.
